Yokogawa AFS40S Field Control Unit
Product Introduction
The Yokogawa AFS40S is a compact, high-reliability field control unit (FCU) designed for decentralized control in industrial automation systems. As part of Yokogawa’s AFS Series, the AFS40S offers efficient data acquisition and processing capabilities directly at the field level, reducing latency and enhancing real-time responsiveness.
Built for integration into Distributed Control Systems (DCS) such as Yokogawa’s CENTUM and Stardom platforms, the AFS40S provides robust control for critical process applications. With a slim profile and modular design, this unit is particularly well-suited for installations with space constraints, while maintaining high I/O processing performance and secure communication capabilities.
